NPort IA5150A/IA5250A Series

Initializing the NPort's IP Address

Determine whether your NPort IA5150A/IA5250A needs to use a Static IP or Dynamic IP (either DHCP or
BOOTP application).
If the NPort IA5150A/IA5250A is used in a Static IP environment, you can use the NPort
Administration Suite, ARP, Web Console, Telnet Console, or Serial Console to configure the new IP address.
If the NPort IA5150A/IA5250A is used in a Dynamic IP environment, you can use the NPort
Administration Suite, Web Console, Telnet Console, or Serial Console to configure the NPort IA5150A/IA5250A
to get an IP address dynamically with DHCP, DHCP/BOOTP, or BOOTP.
ATTENTION
Consult your network administrator on how to reserve a fixed IP address for your NPort IA5150A/IA5250A in
the MAC-IP mapping table when using a DHCP Server or BOOTP Server. In most applications, you should
assign a fixed IP address to your NPort IA5150A/IA5250A.

Factory Default IP Address

NPort IA5150A/IA5250A products are configured with the following default private IP address:
Default IP address:
(IP addresses of the form 192.168.xxx.xxx are referred to as private IP addresses, since it is not possible to
directly access a device configured with a private IP address from a public network. For example, you would not
be able to ping such a device from an outside Internet connection. NPort IA5150A/IA5250A applications that
require sending data over a public network, such as the Internet, require setting up the server with a valid
public IP address, which can be leased from a local ISP.)

NPort Administration Suite

NPort Administration Suite consists of some useful utility programs that are used to configure and manage your
NPort IA5150A/IA5250A.
See Chapter 5 for details on how to install NPort Administration Suite, and how to use this suite of
useful utilities to set up IP addresses and configure your NPort IA5150A/IA5250A Series serial
device servers.

ARP

You can make use of the ARP (Address Resolution Protocol) command to set up an IP address for your NPort
IA5150A/IA5250A. The ARP command tells your computer to associate the NPort IA5150A/IA5250A's MAC
address with the intended IP address. You must then use Telnet to access the NPort IA5150A/IA5250A, at
which point the device server's IP address will be reconfigured.
ATTENTION
In order to use this setup method, both your computer and NPort IA5150A/IA5250A must be connected to the
same LAN. Or, you may use a cross-over Ethernet cable to connect the NPort IA5150A/IA5250A directly to
your computer's Ethernet card. Before executing the ARP command, your NPort IA5150A/IA5250A must be
configured with the factory default IP address (192.168.127.254), and your computer and the NPort
IA5150A/IA5250A must be on the same subnet.
